HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 778,557, dated December27, 1904.

. Application filed June 8, 1904. Serial No. 211,664. I

To all whom it vnay concern.-

Be it known that I, J osnrn SZEPE, a subject of the Emperor ofAustria-Hungary, residing at Allegheny, in the county of Allegheny andState of Pennsylvania, have invented certain new and useful Improvementsin Hose- Gouplings, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention has relation to hose-couplings; and the object of thisinvention is the provision of novel means whereby two sections of pipemay be easily, quickly, and effectually secured together.

A further object of my invention is to provide a hose-coupling whichwill be extremely simple in construction, strong and durable, and highlyeflicient to the many usages to which it is applied, and while myimproved hosecoupling is particularly adapted for sections of hose 1have constructed the same whereby two sections of pipe may be as easilyand effectually secured together as two sections of hose.

The above construction will be hereinafter more fully described, andspecifically pointed out in the claims, and referring to the drawingsaccompanying this application like numerals of reference indicate likeparts throughout the several views, in which-- Figure 1 is asideelevation of my improved hose-coupling. Fig. 2 is an end view looking inthe direction of the arrow of Fig. 1. Fig. 3 is an end view looking inthe opposite direction from that of Fig. 2. Fig. 4 isa side elevation ofmy improved hose-coupling,showing one of the hose-sections beingdetached. Fig. 5 is a top plan view of my improved hose-coupling. Fig. 6is an end view of the uncoupled end of one of the sections,and Fig. 7 isan end view of the uncoupled end of the other section.

Referring to the accompanying drawings, the reference-numerals 1 and 2indicate two sections of pipe to which two sections of hose may besecured in any desired manner, and each one of these sections of pipe isprovided with an enlarged collar 3 and 1, and the face of the enlargedcollar 3 is provided with an annular recess 5, in which a rubber gasket6 is mounted. The shoulder 7 of the collar 3 is provided with an annulargroove 8, the object of which will be hereinafter described. The face 9of the collar 4: is provided with an annular recess 10, and formedintegral with this collar are lugs 11 11, between which is journaled bya pin 12 the contracted end 14 of a lever 15, this lever being providedwith a recess 16 in its end whereby a suitable bar or rod 16 may beplaced therein to facilitate the manipulation of said lever. To thislever are pivoted by a pin 17 the arms 18 18 of a hook-shaped lever 19,the hook portion 20 of which is adapted to engage in the annular groove8 of the collar 3 when the sections are coupled together.

The pipe-section 2 has formed integral with it the lugs 21 21, which areadapted to receive the end of the lever 15 when the pipe-sectionsarejoined together, and the reference-numeral 22 designates a projectionwhich is formed integral withthe collar 4, said projection extendingoutwardly from said collar and has its outer end bent upwardly, forminga hook 23, which also is adapted to engage the annular groove 8 of thecollar 3.

The manner of securing the two sections of pipe together is as follows:The pipe-section 1, which carries the gasket 6, is placed in theposition shown in Fig. 4:, the annular groove 8 of the collar 3 engagingthe hooked end 23 of the projection 22, at which time the hookshaped end20 of the lever 19 is engaged in the annular groove 8, and upondepressing the lever 15 the pipe-section 1 is drawn into engagement withthe pipe-section 2, the rubber gasket 6 entering the annular recess 10and forming a water-tight connection between said pipe-sections, andwhen the pipe-section 1 has been drawn into position the lever 15 isadapted to lie between the lugs 21 21, whereby the end of said leverwill be protected and prevented from striking any objects whereby thesame could be moved to such a position as to uncouple the pipe-sections.By pivoting the lever 15 to the collar 4 the fulcrum-point of the lever19 when in a locked position will lie below the center-line orpivotpoint of the lever 15, and said lever will be normally held in thislocked position until raised to such a height as the fulcrum of thelever 19 is above the center-line of the pivot 12, at which time thepipe-section 1 can be readily removed.

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit of the invention.

hat I claim, and desire to secure by Letters Patent, is-

1. A hose-coupling composed of two sections of pipe having abuttingends, each having an integral collar, one of said collars having anannular groove on its outer face, the other of said collars carrying afixed hook, and a pivoted lever, carrying a pivoted hook, the pivotedhook and fixed hook both engaging said annular groove in the oppositemember, said lever being pivoted to the collar and the said pivoted hookbeing attached to the lever between the end of the lever and the pivotalpoint of the same.

2. In a pipe-coupling the combination of two abutting members one beingformed with a collar having a groove extending around its outer face,the other member carrying on one side a rigid hook adapted to engagesaid groove and on the other side a lever pivoted adjacent the end ofsaid member, lugs on said last-named section between which the lever isadapted to lie when in its depressed position, a bar or rod extendingrearwardly from the free end of said lever and a hook-shaped leverhinged to the first-named lever between its pivotal point and said rodor bar, and adapted to engage said groove, the members being soconstructed and arranged as to be revoluble one on the other when joinedtogether.

In testimony whereof I affix my signature in the presence of twowitnesses.
